Linear Conversion Yields Stuck Pixels

[robekert]

Hi all,
This is my first post on the Canon Boards. I have been lurking for a few months. I have a Canon G1 & G3. I use an iMac 800 Superdrive with PS7. Now to my question.

I was using Canon's File Viewer Utility to process images until I switched to Adobe Camera RAW a few weeks ago. I then saw some posts about Linear vs. Non-Linear conversions. I am under the impression that FVU is Linear and ACR is Non-Linear. I was experimenting with both, on the same RAW images, and discovered that FVU shows 3 stuck pixels on my G1 images that ACR does not. I have converted 5 images all with the same results. The stuck pixels can be corrected easily with the clone stamp in PS7 so that is not the problem.

Does anyone have any insight on this?

Thanks,
Rob

Hi Rob,

According to all that I've read, it seems that G1 images do not support linear conversion. FVU (and Breezebrowser) will do a non-linear conversion regardless of your settings.

Regarding the quality of the converted image, the rumor going around is that ACR simply does a better job, which may explain why you are getting dropped pixels when using FVU but not when using ACR. I haven't yet tried it, so can't say for sure.
